Microfluidic chips
Microfluidic chips made of glass produced by Klearia use a low-temperature bonding process, below 300°C. This technique was developed and patented during the doctoral thesis of Clément Nanteuil, the CEO of Klearia, in 2010. This innovation represents a significant advancement in microfluidic technology, as low-temperature bonding offers several advantages.

The Advantages of Klearia process for custom glass microfluidics chips manufacturing
01
Customization and quality of features
Coupling photolitography with wet etching process offer a large range of design's customization with an ideal roughness and flatness for applications requiring optical observations through a microscope like life sciences for example.
02
Sensitive materials embedment
Lower temperatures reduce the risk of damaging sensitive materials or components embedded within the chips, making the process suitable for a wide range of applications involving sensors and actuators. Ideal for the manufacturing of Lab-on-chips.
03
Reduce your development costs
Due to the complex manufactruing steps realized in cleanroom, glass microfluidics chips are generally high entry costs. In Klearia, we propose to manufacture on a 4'' wafer process line in order to reduce the N.R.E on a new design to test. Ideal for small to mdium volume size!
Characteristics of Glass microfluidics chips
Glass chips have the advantage of withstanding extreme conditions: they are resistant to chemicals, and have higher bulging pressures than conventional polymer microfluidic chips. Moreover, their lifespan is considerably longer compared to almost single-use PDMS microfluidic chips (Polydimethylsiloxane).
